| Abstract: | We investigated inverted bulk heterojunction solar cells fabricated with gold (Au) leaf as laminated top electrodes. We demonstrate that the Au leaf can be successfully transferred from a supporting polyethylene terephthalate (PET) substrate to the surface of poly(3,4-ethylenedioxythiophene) poly(styrenesulfonate) (PEDOT:PSS) due to sufficiently higher work of adhesion with PEDOT:PSS compared to PET. By optimizing the lamination conditions, the contact between the Au leaf and the PEDOT:PSS becomes homogeneous and the power conversion efficiency (PCE) improves. Using Naphtho[1,2-c:5,6-c']bis[1,2,5]thiadiazole based polymer as the p-type semiconductor, the PCE reaches 5.07%. The laminated devices exhibit excellent stability comparable to that of the evaporated devices. |
